Description
Bekanntlich stehen zur Entkeimung von Wasser eine große Reihe von Verfahren zur Verfügung. So· sterilisiert man Wasser durch entkeimende Zusätze oder durch Erhitzen auf bestimmte Temperaturen oder auch durch Bestrahlen mit ultraviolettem Licht. Bekannt ist ferner die vollständige oder teilweise Sterilisierung von Wasser durch dessen Behandlung mit Chlorgas' oder mit Hilfe von. Ozon, das in besonderen Erzeugungsanlagen hergestellt wird.It is well known that water is used for disinfection a wide range of procedures are available. This is how water is sterilized with disinfecting additives or by heating to certain temperatures or by irradiating with ultraviolet Light. The complete or partial sterilization of water by treating it is also known with chlorine gas' or with the help of. Ozone produced in special production facilities will.
Die Erfindung besehreitet in der sterilisierenden Behandlung von Wasser einen neuen Weg1, wobei sie von der Verwendung an sicäi bekannter Mittel und Maßnahmen Gebrauch macht. Das neue Verfahren eignet sich im besonderen Maße bei einem Wasser, das mechanische Verunreinigungen, insbesondere organischer Art, enthält. Es spielt dabei keine Rolle, ob diese verunreinigender]! Bestandteile in feinster oder in gröberer Form vorliegen. Das Verfahren gemäß der Erfindung; eignet sich also insbesondere zur Entkeimung von Flußwasser.The invention besehreitet in the sterilizing treatment of water a new path 1, wherein it makes use of the use of sicäi known means and measures. The new method is particularly suitable for water that contains mechanical impurities, in particular of an organic nature. It does not matter whether this is contaminating]! Components are in the finest or coarser form. The method according to the invention; is therefore particularly suitable for disinfecting river water.
Die Erfindung bestelht in einem Verfahren zur Sterilisierung von Wasser, das sich dadurch auszeichnet, daß das Wasser durchlüftet und gleichzeitig oder nach der Durchlüftung der Einwirkung vom Ultraviolettstrahlen ausgesetzt wird.The invention consists in a method for Sterilization of water, which is characterized by the fact that the water aerates and at the same time or exposed to ultraviolet rays after ventilation.
Die Durchlüftung des Wassers wird zweckmäßig in der Weise vorgenommen, daß die in das Wasser gedrückte oder durch dieses hindurchgeblasene Luft darin möglichst fein zerteilt wird. Die ErfindungThe aeration of the water is expediently carried out in such a way that the in the water compressed air or air blown through it is divided as finely as possible. The invention
geht von der Tatsache aus, daß dabei insbesondere die in dem Wasser vorhandenen,- mechanischen Verunreinigungen Luft absorbieren oder durch Absorption von Luftbläschen sich gewissermaßen mit einer Lufthülle umgeben.is based on the fact that in particular the mechanical impurities present in the water Absorb air or, as it were, surround yourself with an air envelope through the absorption of air bubbles.
Nun ist es zwar schon bekannt, Wasser, z. B. zum Zweck der Enteisenung oder Entmagneti-" sierung, mit Luft zu durchblasen und danach von den sich absetzenden Niederschlagen abzuziehen.Now it is already known to use water, e.g. B. for the purpose of iron removal or demagnetization " to be blown through with air and then to be removed from the precipitating precipitate.
ίο oder zu filtrieren. Bei dem neuen Verfahren handelt es sich jedoch nicht um eine mechanische Reinigung oder um die Ausfällung von nicht erwünschten, im Wasser gelösten Bestandteilen, sondern um die Entkeimung des Wassere, und zwar ohne Verwendung eines zu- diesem Zweck bekanntermaßen! notwendigen, aber bisher in besonderen Anlagen hergestellten Gases, wie Ozon oder Chlor.ίο or to filter. The new process acts However, it is not a mechanical cleaning or the precipitation of undesired im Dissolved constituents of the water, but rather the sterilization of the water, without using it one known for this purpose! necessary, but previously produced in special systems Gas, such as ozone or chlorine.
Der Erfindung liegt die Erkenntnis zugrunde, daß in der ersten Behandlungsstufe des Wassers, nämlich, durch seine Durchlüftung, auf Grund der schon erwähnten Ab- bzw. Adsorption der Luft in bzw. an den Verunreinigungsteilchen die besten Voraussetzungen geschaffen werden, um an außerordentlich vielen Stellen innerhalb desi z.u entkeimenden· Wassers auf Grund der Maßnahme in der zweiten Behandlungisstufe, nämlich, der Ultraviolettbestrahlung, die zeitlich mit der ersten zusammenfallen oder auch von dieser getrennt sein, kann, das wirksame Mittel, nämlich Ozon, entstehen zu lassen.The invention is based on the knowledge that in the first stage of treatment of the water, namely, through its aeration, due to the Absorption or adsorption of the air in or on the contaminant particles already mentioned is the best Conditions are created in order to be able to sterilize in an extraordinarily large number of places within the Water due to the measure in the second treatment stage, namely, ultraviolet radiation, which coincide with the first or are separated from it, the effective agent, namely ozone, can arise allow.
Dadurch wird es in einfacher Weise möglich, die an sich bekannte sterilisierende Wirkung von Ultraviolettstrahlen durch, die bakterizide Wirkung von Ozon, und zwar des in statu nascendi auftretenden Gases, in hohem Maße zu unterstützen und damit eine sehr wirksame Entkeimung des Wassers zu erreichen.This makes it possible in a simple manner to use the sterilizing effect of ultraviolet rays, which is known per se through, the bactericidal effect of ozone, namely that which occurs in statu nascendi Gas, to a great extent and thus a very effective disinfection of the water reach.
Es steht nichts im Wege, die Bestrahlung dcr Luft für die Durchlüftung' des Wassers mit Ultraviolettstrahlen gegebenenfalls auch schon vor oder während des Mischens mit dem zu entkeimenden Wasser durchzuführen.Nothing stands in the way of irradiating the air for aeration of the water with ultraviolet rays possibly even before or during the mixing with the germ to be disinfected Water carry out.
